Produktbeschreibung

The PiGlow is a small add on board for the Raspberry Pi that provides 18
individually controllable LEDs. You can use it for all sorts of things!
And of course, it fits inside a Pibow!

There are tons of things you can do with it:

Mood lighting / ambiance

Showing current system load

Notify you of events like mentions in tweets or incoming e-mail

Feedback the status of scripts/daemons running on your Pi

Works great when VESA mounted to provide a cast against a wall

...and pretty much anything else you can think of!

This board uses the SN3218 8-bit 18-channel PWM chip to drive 18 surface
mount LEDs. Communication is done via I2C over the GPIO header with a
bus address of 0x54 (Python example code provided). Each LED can be set
to a PWM value of between 0 and 255. Comes fully assembled and ready to
rock.
